Thanks. But I went 163mph with the "cheap" engine.

We've had a bad year at Elmo, not once could we get full power out of the engine.
The engine shuts 1/3 of fuel off at 153mph (and stays down) for unknown reasons, and only at Elmo. There is something hidden in the factory computer that I can't see.
After two 14x passes slowing down through the traps, I "fixed" it by upping the fuel 33% everywhere. Uh, what about when I'm less than 153? OPPSS!! It did this SnapCracklePop routine until it got up to speed. So I traded HP going up to 153, for HP after 153, hence the 157. I'm pretty sure we will break 175mph with this setup at Elmo, I just can't prove it.
